Custom TV Show Directory Structure & Excluding Files

Hey guys, I just started using XBMC and I'm loving it, if anyone of you guys can help me with the following, it'd be great;

The directory structure of My TV Shows folder is in the way;

<Drive>\<Television>\<Person of Interest (2011) [HD_TV]>\<Season 1 (2011-2012)>\<01 Pilot.mkv>

-- OR --

<Drive>\<Television>\<The Simpsons (1989)>\<Season 13 (2001-2002) [HD_Blu-ray]>\<01 Treehouse of Horror XII.mkv>

How do I add reg exps for the above in the advanced settings file ?

#2

How do I exclude certain sub folders within a source ?

eg.

<Drive>\<Movies>\<Avatar>\<Bonus>

I added Movies as source but I don't want the Bonus folder to be scanned.

How do I do that ?

Thanks Guys.
